Certain terms and phrases used in this chapter are hereinafter defined and explained. Otherwise, the words in this chapter shall have the meaning commonly attributed to them.
BASE FLOOD
The flood having a one-percent chance of being equaled or exceeded in any given year.
BASE FLOOD ELEVATION

As related to substantial improvements, the cost of any reconstruction, rehabilitation, addition, alteration, repair or other improvement of a structure shall be established by a detailed written contractor's estimate. The estimate shall include, but not be limited to: the cost of materials (interior finishing elements, structural elements, utility and service equipment); sales tax on materials, building equipment and fixtures, including heating and air conditioning and utility meters; labor; built-in appliances; demolition and site preparation; repairs made to damaged parts of the building worked on at the same time; contractor's overhead; contractor's profit; and grand total. Items to be excluded include: cost of plans and specifications, survey costs, permit fees, outside improvements such as septic systems, water supply wells, landscaping, sidewalks, fences, yard lights, irrigation systems, and detached structures such as garages, sheds, and gazebos.

Directly by the Secretary of the Interior in states without approved programs.
LOWEST FLOOR

MANUFACTURED HOME
A structure, transportable in one or more sections, which is built on a permanent chassis and is designed for use with or without a permanent foundation when attached to the required utilities. The term also includes park trailers, travel trailers, recreational vehicles and other similar vehicles or transportable structures placed on a site for 180 consecutive days or longer and intended to be improved property.
MANUFACTURED HOME PARK OR SUBDIVISION
A parcel or contiguous parcels of land divided into two or more manufactured home lots for rent or sale.
MARKET VALUE
The market value of the structure shall be determined by an independent appraisal by a professional appraiser prior to the start of the initial repair or improvement, or in the case of damage, the value of the structure prior to the damage occurring.
MEAN SEA LEVEL (MSL)
The North American Vertical Datum (NAVD) of 1988 or other datum to which base flood elevations shown on a community's Flood Insurance Rate Map (FIRM) are referenced.

SPECIAL FLOOD HAZARD AREA (SFHA)
The land in the floodplain within a community subject to a one-percent or greater chance of flooding in any given year. SFHAs are determined utilizing the base flood elevations (BFE) provided on the flood profiles in the Flood Insurance Study (FIS) for a community. BFEs provided on the Flood Insurance Rate Map (FIRM) are only approximate (rounded up or down) and should be verified with the BFEs published in the FIS for a specific location. SFHAs include, but are not necessarily limited to, the land shown as Zones A and AE. The SFHA is also called the "area of special flood hazard."
START OF CONSTRUCTION
Includes substantial improvement and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition placement, substantial improvement or other improvement was within 180 days of the permit date. The "actual start" means either the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of excavation, or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers, or foundations or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.
STRUCTURE
A walled and roofed building, including a gas or liquid storage tank that is principally above ground, as well as a trailer.
SUBSTANTIAL DAMAGE
Damage of any origin sustained by a structure, whereby the cost of restoring the structure to its pre-damaged condition would equal or exceed 50% of the market value of the structure before the damage occurred.
SUBSTANTIAL IMPROVEMENT
A. 
Any repair, reconstruction, or improvement of a structure, taking place over a five-year period, the cost of which equals or exceeds 50% of the market value of the structure either:
(1) 
Before the improvement or repair is started; or
(2) 
If the structure has been damaged and is being restored, before the damage occurred.
B. 
For the purpose of this definition, "substantial improvement" is considered to occur when the first alteration of any wall, ceiling, floor or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. The term does not, however, include either:
(1) 
Any project for improvement of a structure to comply with existing state or Town health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions; or
(2) 
Any alterations of a structure listed on the National Register of Historic Places or the Connecticut State Inventory of Historic Places.
VARIANCE
A grant of relief by a community from the terms of the floodplain management ordinance that allows construction in a manner otherwise prohibited and where specific enforcement would result in unnecessary hardship.
VIOLATION
Failure of a structure or other development to be fully compliant with the community's floodplain management ordinance. A structure or other development without required permits, lowest floor elevation documentation, floodproofing certificates or required floodway encroachment calculations is presumed to be in violation until such time as that documentation is provided.
WATER SURFACE ELEVATION
The height, in relation to the North American Vertical Datum (NAVD) of 1988 (or other datum, where specified), of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas.
